Abstract
The utility model discloses a novel low-interference filter, comprising a casing and a base, wherein the base is arranged in the casing; the base is provided with at least two windings which are arranged at interval and in parallel, and a shielding part is arranged between the two windings. The utility model has the advantages of simple structure and skillful design; the windings are arranged at interval, the shielding part is arranged between the windings, and each winding forms an independent part, thereby effectively avoiding generating magnetic field to form mutual interference, greatly enhancing the working stability, protecting other electronic assemblies, and prolonging the service life; in addition, the top of the casing is provided with an opening, so the air can well ventilate, and the heat radiation efficiency is enhanced; the bottom of the casing is provided with wiring terminals, so the installation and connection or welding are convenient, the product quality is ensured, and the safety hazard is eliminated.
Description
Technical field
The utility model relates to filter, is specifically related to the new mode filter of a kind of low interference.
Background technology
In recent years, high-tech industry is prosperous day by day, and the use chance of various electronic product (as computer) heals and becomes frequent in the daily life.Because electronic product has comprised many electronic building bricks, and each electronic building brick all can produce a large amount of Electromagnetic Interference (EMI), and is especially all the more so in the power end part of electronic product.A large amount of Electromagnetic Interference are not only seriously disturbed the running of each electronic building brick own, and very the person will seriously disturb the interior circuit of electronic product, may cause electronic product to damage or fault what is more.When the Electromagnetic Interference of electronic product is serious, also can cause other electronic products runnings unusual or damage.Therefore, the power-supply filter of high frequency is installed all in the general electric equipment products, in the hope of reducing the influence of Electromagnetic Interference for electronic product.
In the known techniques, the filter of existing ET, UT, the various type shapes of EE, its coil are to concentrate and are provided with, and easily produce magnetic field and cause the phase mutual interference, and stability is not good, even causes other electronic building brick impaired; In addition in the restriction of its traditional structure, it is very difficult to be welded to connect action operation such as line, is difficult to guarantee product quality, causes the potential safety hazard of power-supply filter.
In sum,, make that the installation process of power-supply filter is very difficult, and easily when being welded to connect line and filtering unit, drop bead in housing because the design of the structure of now power-supply filter housing is bad, and then problems such as generation yield and fail safe.Hereat, how to improve the shell structure of power-supply filter, and then make the installation process of power-supply filter more easy, the problem that just becomes industry for this reason to need to be resolved hurrily.
The utility model content
The purpose of this utility model is, at the above-mentioned deficiency of existing filter, provides a kind of simple in structure, design science, stability is high and the new mode filter of low interference that can be easy for installation.
For achieving the above object, technical scheme provided by the utility model is:
The new mode filter of a kind of low interference, it comprises that a housing and places the pedestal in this housing, has at least two coiling groups side by side at interval on the described pedestal, and between two coiling groups a shielding part is set.
Described coiling group comprises that an iron core, a bobbin winder base and are wrapped in the coil on this bobbin winder base, and described bobbin winder base is set on the iron core.
